Hi, does anyone has by any chance a drum kit def-score template which is compatible with Musescores Instruments "Drum Kit (large)"? Thanks for help. Achim

No replies on this one yet? I don't use this technique myself but you can use lists of lists to combine time-signatures with the three-element list option - see the def-score helpfile: time-signature is either a two list, e.g. (4 4), or a list of three-lists, e.g. ((4 4 3) (4 8 1) (3 4 1)), where the first two element of each list are the numerator and denominator of the time signature, and the element is the number of bars. The bar count maybe omitted from the final time signature. so you could do-- :time-signature ((3 4 1) (1 8 1) (4 4 1) (1 16 1)) As a rule, the Lisp nested lists allow you to combine in different ways - but check the relevant help files for the sorts of options. This is integers in lists so straightforward. bw Andrew

I've searched the archive and saw that there was some discussion about implementing nested tuplets for version 2.0, but nothing that ever indicated that they were actually implemented. I cannot seem to make them work with version 4.0 no matter what I try. Should they work? If so, would someone be willing to post an example? Thanks, -Beth

Hi Julio, One possibility is to use the MAYBE-SECTION function within your function. However, Janusz has more powerful tricks to add :section and :exclude in functions. 😊 Additionally, I believe it would be beneficial to include a slot for possible intervals in this function, similar to the ones we have in the length-divide and length-subdivision functions. Best Stéphane

Here is what I need ! (setf mat '((h c4 q. d4 e e4 -q w c4 h d4 q e4 -q)(h c4 q. d4 e e4 -q w c4 h d4 q e4 -q)(h c4 q. d4 e e4 -q w c4 h d4 q e4 -q))) (do-section '(0 1 0) '(motive-subdivision x '(1/8)) mat)

Janusz, is there some general function to apply selectively any function to a list ? It would be useful in conjunction to this. For example, selectively applying the motive-subdivision in the first and third measure of a list while mantaining the rest of the list original. A kind of general bypass to any kind of list. Thanks in advance,

Already in my extensions folder ! Thanks a lot ! Very inspiring !

I'm just starting out with OMN so please bear with me here. I don't see a way to represent additive meters like 3/4+1/8 or 4/4+1/16 in the :time-signature argument to def-score. Is there a way to do this? Thanks, -Beth

Dear Jesper, Thanks a lot for your beautiful solution. It worked great ! Nice examples too ! Janusz, please put this in the core system in the next update if everybody agree ! Best, Julio

a (perhaps poor) attempt at a function.

Dear All, Here is a proto-function idea... If Janusz or someone are interested in transform it in a core function, I think it could be interesting... Sometimes I like to take a motive or chorale texture and use it to make a kind of accompaniment or texture ala Reich. I created my way to do it, but it could be perfected in a better function and integrated in the core system. Here is the idea: ;; Motive (setf mat '(h c4 q. d4 e e4 -q w c4 h d4 q e4 -q)) ;; small value (setf fig-value '(e)) The "proto-function". What I could not achieve was how to make it respect the rests in the motive, but it works for generating the texture, respecting the pitch and length boundaries of the motive. (flatten (make-omn :pitch (omn :pitch (omn-to-time-signature mat (get-time-signature (omn-to-measure (length-legato mat) (flatten (length-legato (omn :length mat))))))) :length (omn-to-time-signature (length-span (get-span mat) (gen-repeat 200 fig-value)) (get-time-signature (omn-to-measure (length-legato mat) (flatten (length-legato (omn :length mat)))))) )) RESULT (e c4 mf c4 c4 c4 e d4 mf d4 d4 e e4 mf e4 e4 e c4 mf c4 c4 c4 c4 c4 c4 c4 e d4 mf d4 d4 d4 e e4 mf e4 e4 e4) It could be perfected to result this: (e c4 mf c4 c4 c4 d4 d4 d4 e4 -q e c4 c4 c4 c4 c4 c4 e c4 c4 d4 mf d4 d4 d4 e4 e4 -q) Same texture with the fig-value set do 16th note (setf fig-value '(s)) Best wishes, Julio

Thank you for the feedback. I have had that work. In particular rebooting helped briefly, but it just keeps coming back! I did also confirm that the MIDI Mode is Off in the MIDI Sync tab in Settings. I believe that's what we're talking about.

loop macro isn’t very Lispy, so it isn’t really suitable for Ncode. We could add simple loop templates like repeat etc. but this can be done with other functions.

Set the MIDI clock to OFF: Mode Off

close and restart Opusmodus.

Am I doing something weird, or is it normal for the MIDI player to skip notes and play erratically like this (evidence in video below)? I only started noticing it recently. I'm running OpusModus on a MacBook Pro (Tahoe 26.1) M1 with 32 GB of RAM. This particular work is set up as follows, not including all the variable definitions: (def-score drums (:key-signature 'chromatic :time-signature '(4 4) :tempo 120) (kik :omn bd :sound 'gm :channel 10 :program 0 :port 0) (snr :omn sn) (hht :omn hh) (clap :omn clp) (ohht :omn ohh) (clav :omn clv) (hht2 :omn hh2) ) (display-midi 'drums) Thank in advance for any advice, Brenden opusmodus performance issues.mov

It would be fun if we could get instant feedback when changing function parameters. For example if I press enter in a parameter field and the graph window is open, it updates with the new result. Or, clicking the Refresh All button refreshes the graph view if it's open or even the notation view. I know instant feedback isn't the intent of a program like Opusmodus, but Ncode is breaking new ground! I think this would be a fun interactive experience, if it's possible.

Could I get an example of the proper syntax of the body of the loop function?

The code colorization works only at the Opusmodus editor level.

Done in 4.0.30673 Contextual variable insertion (Function and Argument fields) To reuse existing history variables while composing a new function call, NCODE provides a contextual insertion menu in the Function and Argument fields. How to use: right-click inside the Function field or an argument field to open a contextual menu of available history variables. Insert behaviour: selecting a variable inserts its name at the current caret position. The existing field text is preserved (it is not replaced). Purpose: this supports rapid reuse of previously computed materials without recalling (loading) the variable’s originating function. Notes: insertion is purely textual. It does not evaluate the function and it does not alter the history selection.

I like the automatic variable name generator. Since the intent of NCODE is to facilitate exploring musical ideas quickly in an interactive interface, would it make sense to facilitate adding existing variables to new functions? Either drag and drop, point and click, or drop down list, or similar.

Hello is there a way to export the code in color as a PDF? When I print it to PDF it comes out black and white. But it would be extremely helpful if I can print it to PDF in color. Thank you!

Fixed in 4.0.30671

Additional Ncode functionality (Ncode Manual): 2.2.4 SETF mode, templates, and pages NCODE provides a template-driven mode for constructing structured values via SETF pages. This mode is used when the Function field is SETF and a template is selected. Rather than entering a single expression, the user fills a set of pages; NCODE then reconstructs a quoted value and evaluates a (setf …) form. Figure 3 SETF mode, templates and pages. SETF pages provide a UI method for building complex, repeatable list structures (collections of labelled items) without manual list syntax. This is particularly useful when the value is naturally expressed as multiple items that must be ordered. Templates A template defines: the number and organisation of pages, and the fields available on each page (key–value pairs). Selecting a different template changes the page layout and the meaning of the fields. The selected template and page contents are saved in the .omnc session and restored when reopened. Each page corresponds to one logical item in the resulting value. Next page creates a new item. Remove page removes an item. Empty pages are ignored when the final value is constructed. Field values Fields accept numbers, strings, keywords, lists, and symbols. Symbols entered without a leading quote may be treated as variable references (for example, previously stored history variables). When a literal symbol is required, enter it as a quoted symbol. Constructed value When evaluated, NCODE converts the populated pages into a single quoted form: if one page is populated, the value becomes a quoted single item; if multiple pages are populated, the value becomes a quoted list of items. NCODE then evaluates the corresponding (setf …) form, storing the result in the history like any other entry. Reproducibility SETF pages are stored as structured page data in the session. When reloading a session or using Refresh All, NCODE reconstructs the same quoted value from the saved pages and re-establishes consistent bindings. https://opusmodus.com/forums/ncode/ NCODE is still in beta, but with every update, it is becoming a more stable tool.

OK, thanks for help! My eyes were too much fixed on (asdf:load-system :tot). With etu's fix I now could evaluate both Stephane's and etu's scores. Henry
